“…The XRD analysis of Pd1/PU did not detect any standard peaks associated with the presence of Pd in a monatomic form, which is consistent with the HAADF-STEM data (Figure 2a). The presence of urethane linkages was confirmed by the peak at 1726 cm −1 in the FI-IR spectra (Figure 2b) and there were no other functional groups in the studied polyurethanes that could significantly affect the catalyst performance [42][43][44][45][46]. Furthermore, there was no substantial alteration in the structural attributes of the catalysts prior to and subsequent to calcination.…”

As worldwide plastic pollution continues to rise, innovative ideas for effective reuse and recycling of waste plastic are needed. Single-atom catalysts (SACs), which are known for their high activity and selectivity, present unique advantages in facilitating plastic degradation and conversion. Waste plastic can be used as a support or raw material to create SACs, which reduces waste generation while simultaneously utilizing waste as a resource. This work successfully utilized waste plastic polyurethane (PU) as a support, through a unique Rapid Thermal Processing Reactor (RTPR) to synthesize an efficient Pd1/PU SACs. At 25 °C and 0.5 MPa H2, Pd1/PU displayed outstanding activity and selectivity in the hydrogenation of styrene, as well as remarkable stability. Pd1/PU performed well in hydrogenating a variety of common substrates. These findings highlight the great potential of SACs in plastic waste reuse and recycling, offering intriguing solutions to the global plastic pollution problem.
